DETAILED DESCRIPTION

According to an exemplary embodiment, calendar-based power reserve for mobile communications devices is provided. The calendar-based power reserve provides a means to reserve and lock an amount of battery power in a mobile communications device for utilization during an upcoming scheduled event where the user has indicated within the calendar entry that his/her attendance via the mobile communications device is important or mandatory. These and other features of the calendar-based power reserve will now be described.

Turning now to FIG. 1, a system 100 upon which the calendar-based power reserve may be implemented will now be described in an exemplary embodiment. The system 100 of FIG. 1 includes mobile communications devices 102 in communication with one or more networks 106. As shown in FIG. 1 for purposes of illustration, the mobile communications devices 102 include a tablet computer 102A and a cellular telephone 102B. However, it will be understood that other mobile communications devices may also be utilized in implementing the exemplary calendar-based power reserve features. For example, a personal digital assistant (PDA), smart phone, laptop, or other device having wireless calling capabilities may be used. The mobile communications devices 102 may be implemented using computer processors operating in response to computer programs stored in a storage medium accessible by the processors.

Each of the mobile communications devices 102 include a chargeable battery (not shown) as are typically found in such devices. Each of the mobile communications devices 102 also includes a power management component 104, a calendar application 108, and a power reserve application 110.

The power management component 104 monitors the battery power of the mobile communications device 102 and reserves an amount of battery power as directed by the power reserve application 110. The power management component 104 may be implemented in hardware, software, or a combination thereof. The power management component 104 is configured to communicate with the power reserve application 110 and perform power reservation activities in response to instructions from the power reserve application 110, as will be described further herein.

The calendar application 108 provides a user interface that allows user of the mobile communications device 102 to schedule and track activities or events via the mobile communications device 102. The user interface may be configured to provide different calendar views (e.g., daily, weekly, monthly) of scheduled events, as well as related functionality, such as setting alerts or reminders, scheduling recurring events, and sharing calendars with other individuals or mobile communications devices. The calendar application 108 may be a stand-alone application that exists only on the mobile communications device 102 and is accessible only by the owner of the mobile communications device 102. In another embodiment, the calendar application 108 may be configured to synchronize entries and data with a remote calendar application, for example, where the mobile communications device 102 owner is among a group of people that have access to the calendar (e.g., a team of individuals all have access to a calendar for team meetings, and one of the team members is the calendar owner).

The power reserve application 110 is configured to communicate with the calendar application 108 and the power management component 104 to identify scheduled events that are considered a priority, to calculate an amount of power needed to conduct scheduled events having the priority, and to reserve the calculated amount of power so that the amount of power is ready and available to the user at the time of the scheduled event. The power reserve application 110 may be configured as a plug-in to an existing calendar application. While shown as separate components, it will be understood that the power reserve application 110 and the calendar application 108 may be configured as a single, integrated application that performs all of the features of its individual components.

The networks 106 may include any type of known networks including, but not limited to, cellular, satellite, and terrestrial. The networks 106 may include a wide area network (WAN), a local area network (LAN), a global network (e.g. Internet), a virtual private network (VPN), and an intranet. The networks 106 may be implemented using any kind of physical network implementation known in the art.

Turning now to FIG. 2, a process for implementing calendar-based reserve features will now be described. The process described in FIG. 2 assumes that a user has opened the calendar application 108 and has entered a new event into the calendar application 108 of the mobile communications device 102. Alternatively, the user may have received a meeting invite from another user that designates a particular time slot, and the user accepts the meeting invite (i.e., new event) which, in turn, causes the calendar application 108 to schedule the meeting into the user's calendar. The new event is a telephone call to be placed on the date (and optionally time) entered into the calendar application 108. The new event may be scheduled into the calendar application 108 via a user interface screen 300, which is shown in FIG. 3.

The user interface screen 300 includes input fields 304 that prompt the user to enter the subject of the event (e.g., “Call Hiroki-san”), as well as starting dates/times and ending dates and times associated with the call (i.e., a call time and duration). Alternatively, if the new event is a meeting invite, as described above, the inputs of the starting dates/times and the ending dates and times may be omitted. The user is then prompted by the power reserve application 110 via the calendar application 108 to designate whether the scheduled event is a priority. The user designates a priority by selecting a priority indicator 306, which is illustrated in FIG. 3 as “ENSURE POWER FOR THIS ENTRY?” The priority indicator determines whether the power reserve application 110 will reserve power specifically for the scheduled call. The user makes this selection when it is imperative that the mobile communications device 102 have sufficient power to conduct the scheduled event. Once the event has been scheduled, the user can save the event into the calendar application 108 by selecting “SAVE” 308 on the user interface screen 300.

Returning now to FIG. 2, the power reserve application 110 identifies the new calendar entry scheduled into the calendar application 108 as a telephone call at step 202. As shown in a user interface screen 400 of FIG. 4, a telephone call indicator 410 is adjacent to the scheduled calendar entry 404. At step 204, the new calendar entry is stored in the calendar application 108.

At step 206, the power reserve application 110 checks to see if the priority indicator 306 has been set by the user for this event. If the priority indicator 306 has been set for the new calendar entry at step 204, the power reserve application 110 notifies the power management component 104 of the date (and time, if applicable) of the calendar entry at step 208. In one embodiment, the power reserve application 110 calculates an amount of power to reserve for the calendar entry at step 210. This may be implemented using the duration of the call as specified in the calendar entry (e.g., via start and end times from inputs 304), and the amount of power needed for this duration is estimated by the power reserve application 110.

At step 212, the power reserve application 110 instructs the power management component 104 to reserve an amount of power for the scheduled calendar entry. If the calendar entry specifies a time duration and the power reserve application 110 has calculated an estimated amount of power needed for the scheduled event, this estimated amount is the amount of power reserved for the event.

The power reservation may be implemented using various techniques. In one embodiment, e.g., the power may be reserved by logically partitioning the storage of the battery and relocating the reserved amount of power to a particular partitioned location. Alternatively, the power reservation may be implemented by updating the battery power indicator on the mobile communications device to reflect a decrease in the capacity without relocating the reserved power to a different storage location. In this example, the capacity of the battery power remains the same but the battery power indicator reflects that a lesser amount of battery power is available.

In one embodiment, the power management component 104 may maintain a database (e.g., stored in the mobile communications device 102) including the meeting time slot and the percentage or amount of power reserved.

The power reserve application 110 instructs the power management component 104 to update a battery power indicator 408 on the mobile communications device 102 to reflect a capacity of the battery. The capacity reflects the current amount of available power for the battery minus the amount of power to be reserved for the scheduled call and any intervening calls in which power has been reserved.

The power reserve application 110 displays a reserve indicator 406 adjacent to the scheduled calendar entry in which the priority indicator 306 has been set.

At step 214, once the amount of power has been reserved, or alternatively, if the priority indicator 306 has not been set (from step 204), the power reserve application 110 monitors upcoming scheduled events (calls) in the calendar application 108. This may be implemented by traversing the calendar entries and checking for those marked as telephone calls by the calendar application 108.

At step 216, in response to the monitoring, the power reserve application 110 determines whether the current time is equal to or within a specified threshold of time identified for a scheduled call, e.g., using the mobile communications device's 102 internal clock. If not, the power reserve application 110 continues to monitor the scheduled calls in the calendar application 108. Otherwise, at step 218, the power reserve application 110 instructs the power management component 104 to release the amount of reserved power so the user may conduct the call without interruption caused by inadequate battery power.

In one embodiment, if a user's event is scheduled for a duration that is longer than the duration for which remaining batter power is available, the power reserve application 110 may notify the user via the mobile communications device 102 that it will reserve all remaining battery power, and/or the power reserve application 110 will prompt the user to immediately recharge the mobile communications device 102. If the user moves or alters a scheduled event, the power reserve application 110 may be configured to update the instructions to the power management component 104 to reserve the amount of power for a different date/time or duration, or adjust the amount of power reserved accordingly. If the event is cancelled, the amount of reserved power is released back into the pool of battery power available, and the battery power indicator 408 is updated to reflect the change in amount of available power.

In one embodiment, the power reserve application 110 may be configured to enable a user to override or disable the priority indicator 306 at any time to ensure there is sufficient power available should the user unexpectedly need the additional power.

In another embodiment, the power reserve application 110 may be configured to provide user-selectable policy settings for implementing the power reserve features. For example, other priority settings may be employed, such as “optional attendance” whereby the power reservation for “must attend” meetings (e.g., through option 306) would take precedence over those designated as “optional attendance,” and any power reserved for “optional attendance” meetings may be reassigned to “must attend” meetings based on the overall amount of power available at a given time. Other policy settings may include power reservations based on characteristics of a meeting (e.g., my attendance is mandatory for meetings with my executives/manager), a user role in a meeting (e.g., an initiator of the meeting must have power reserved for the meeting), and a genre of the meeting where an amount of power reserved is determined based specifically on the genre (e.g., ensure a greater percentage of power reserved for meetings implemented using video, web hosting, or other applications requiring greater amounts of power). Tentatively accepted meetings may be treated by the power reserve application 110 in a similar manner as “optional attendance” meetings except that the power reservation is implemented once the meeting status goes from “tentative” to “accepted.”

By providing a priority indicator option, users of mobile communications devices can ensure they will have sufficient battery power without having to continuously monitor their devices.

Technical effects of the invention include calendar-based power reserve features that enable a user of a mobile communications device to reserve and lock an amount of battery power in the mobile communications device for utilization during an upcoming scheduled event where the user has indicated within the calendar entry that his/her attendance via the mobile communications device is important or mandatory. The calendar-based reserve provides a user interface via a calendar application in which a priority indicator is selected for such important or mandatory calendar events. The calendar-based reserve features provide the means to calculate an estimated amount of power needed for a scheduled calendar event using a time duration specified in the calendar event.
